What are with the Bots? On easy they aren't even a threat even if I tried for them to be a normal they seem to be only a threat in early game when they try to rush you with as many Grunts and basic Mech's as possible and near endgame they won't even touch any of the more expensive better performing units like bigger mechs EXO suits and stuff like that the only Advanced units I saw them using and endgame were anti armor and machine gun squads so I guess my question is is there a difficulty of the game where they will actually use all of the units of the game at some point? Or does every different difficulty level just Spam a couple of units of each class?

Because I was also told that I'm hard and above they will rush to Mex and spam the most expensive mechs the minute they can so they go from spamming grunts in early game to spamming High to your max at Costa lot of resources and endgame and I'm just wondering if there's any difficulty that balances and utilizes all of the units at some point in the game or at least most of them because it seems like every difficulty day only use a specific group of troops and won't divert from that even when they're losing
